I installed ME MAPI Connector in Windows 10 with Outlook 2016 and the MAPI option does not appear as an account-type option when I try to add account from either Outlook 2016 directly or Email control panel.

I am having a similar issue. It looks like Microsoft have changed the add new account options in outlook 2016 which does not allow the selection of the mailenable MAPI connector.

It has also broken adding activesync accounts to Outlook as well - you must have autodiscover working (which mine is) but it does not accept the UPN format for the username - remote connectivity analyzer is showing a 401 error.

I'm currently using Outlook 2016 and Windows 10. I had to create the account through Mail in the control panel. Then selecting email accounts then clicking new. It showed MailEnable server in there as an option under other.

Still no go for me i'm afraid. I still get the new outlook add account wizard with no option to use the mapi add-in (or exchange activesync with manual server settings for that matter). This was working up until a month or two ago, then Microsoft [insert bright idea here] and now it is problematic.
